Does reducing your mem clocks hurt the performance? If so, then it wouldn't be worth it, anyway.

Yeah that's the thing. I have a feeling that the core clock is the most important, but reducing the memory too much is forcing me to keep my core at 950mhz.

Sorry, my point was in reference to needing some gigantic tower to keep VGA's cool. A cooler like the Accelero or Zalman 3000 are enough cooling that heat (and noise too) isn't a limiting factor for over volting, O/C'ing.

coincidentally MrK6 pointed out that these guys did some epic 580 OC'ing on air by strapping a tower onto the card:

My point isn't so much that today's stuff would be all the better with it...strapping a tuniq onto a 486 wouldn't necessarily enable us to OC it to 500MHz either...but without a doubt we are paying for the engineering expenses that are going into the development of 1" tall HSF for our cards and those costs would be less if they had more room, the noise would be less with bigger fans at lower rpm, and the potential for higher heat dissipation would compel engineers to develop faster and more power-hungry chips for gen N+2.

That would be a lot of weight to suspend from the motherboard. I would be worried that something would warp or crack. You would also lose all of your PCI slots.

I actually did something like that with my G80 when my HSF died, but I used a much smaller HSF than that one. It did a decent job, but it didn't cool the memory.

^^ that is one messed up looking rig. Not gonna happen in my room! Sorry it's a cool exercise to get some pics for the geeks to look at, but hell no i'm doing that

10% more performance for free, whats to think about.

a few things to think about. 10% more performance in raw power probably means 5% in-game, max. And with my gaming, 5% in-game gain wouldn't make a difference. So I'm burning electricity for nothing (unless it's just to run benchmarks).

second, I have a Palit, which arguably uses the SMALLEST freaking heatsink of all the heatsinks on these 460s, and yes at 850 MHz it does run hotter than other 460s out there. Why do I get a Palit then? Because at $109 for a 1GB version, it was a steal regardless.

If I had an MSI Hawk or Gigabyte with twin fans, then I woldn't think much trying for 1000 Mhz!

lastly, this Palit 460 only serves as my 2nd (reserved) gaming system out in the living room hooked up to a 42" 1080p tv where I mainly use it for driving/racing games, and most of these games don't require more gpu power.

so... still thinking...

Come on, mate, we aren't talking about a 580, in your case. You have a 460, and that Accelero is going to keep it cool til it doesn't want anymore volts or higher clocks. You aren't planning on dumping that much voltage into it, are you?

There is a heat sink out there that is designed similar to a CPU cooler. I can't remember the brand, ATM. It even has a separate tower for cooling the VRM's. It's still expensive though. In the end they are basically sold by the pound (or Kilo, depending on how you look at it) Not particularly crossfire/SLI friendly, either.

I'm not sure what it is exactly that you feel compelled to protest here in regards to the dialogue I aimed to communicate in this thread. :confused:

Somehow the purpose of my posts in this thread has been lost in translation, I'm convinced.

I already touched on the PCIe slot spacing concerns, touched on the cost-savings benefit to be had in removing the engineering constraint on HSF height that currently exists, as well as mentioned the prospect of having quieter HSF operation.

With so much upside potential to an otherwise entirely hypothetical discussion (because of the PCIe spec) I fail to see why the minuscule list of downsides need be pressed front and center. I am not talking about adding a tower to my puny 460...I was talking about the enthusiast community in general, they have options with their CPU's that simply aren't available for their GPU all because of a somewhat artificial spec that determines the max allowed HSF height.

I guess I just don't agree with most of the points in your assessment. Just thought I'd give my opinion. I'm not compelled to protest though, as you put it. I won't pursue it further. Sorry to have annoyed you.

It amazes me the gap between the air-cooling options for CPU's versus those for GPU's.

I can bolt a 6" tall tower HSF onto my CPU that dissipates maybe 160W fully OC'ed but the best retail air-cooling I can do for my 200W OC'ed GPU is a HSF that is maybe 1" tall.

Imagine what we could do if the after-market HSF options expanded to include the equivalent of Tuniq Towers and Thermax Eclipse II.

Instead we get the choice between crappy tiny GPU HSF's or jumping all the way up to $300-$500 watercooling.

(and yes I understand that clearance and PCIe spacing is the culprit here, just saying it would be nice if this needless bottleneck in air-cooling were engineered out of the equation as has been done with CPU's)

Thanks for this. I presumed, it seems incorrectly, that high-end GPU cooling was much better than even high end CPU cooling (not including water, liquid nitrogen, -20C ambient temps or whatever).

Imagine the noise benefits too, if you could do a push/pull Megahalems setup on your videocard with 2x nexus fans? I wonder if that'd be sufficient (if only the cooler fit the videocard appropriately). I'm quite sensitive to leafblower effect, even with my UE10 Customs inserted (noise isolation, inner ear audio bliss).

This is a very interesting idea, as I'm slowly piecing together my new rig. Trying to combine blistering speed with power efficiency and as little noise pollution as possible is going to take me a while!

Thermalright Shaman, with TR vrm cooler?
